ATTACHMENT FOR BOTTLE-WASHING MACHINES.

Specification of Letters Patent.

Application filed June 8, 1914. Serial No. 843,778.

To all whom it may concern:

{Be it known that I, STEPHEN MARTI- NELLI, Jr., a citizen of the United States, residing at lVatsonville, in the county of Santa Cruz and Stateof California, have invented a new and useful Improvement in Attachments for Bottle-Washing Machines, of which the following is a specification.

This invention relates to bottle Washing machines, and more-particularly to an attachment for a bottle washing machine, and one of the principal objects of the invention is to provide an improved attachment for a well known type of bottle washing machines, by means of which the rust which ordinarily collects at and adjacent to the crown groove of a bottle neck may be removed, simultaneously with the cleansing of the interior of the bottle.

Another object of the invention is to provide an attachment of the class described,

affording means whereby the bottle neck may be cleaned by means of rotary brushes.

Another object of the invention is to provide a device of the class described including a rotary brush for cleaning the bottle neck simultaneously with the cleansing of the interior of the bottle, and means whereby the brush may be driven from the spindle of the machine.

Still another object of the invention is to provide an attachment of the class described including rotary brushes of an improved nature, means for adjusting the brushes, means for attaching the brushes to a bottle washing machine, and means for driving the brushes from the spindle of the machine.

A further object is to provide a device of the class described which will be simple, durable, inexpensive to manufacture, efficient in operation, and one which may be attached without the use of special tools and without the employment of. skilled labor, and without necessitating changes in the construction of the bottle washing machine.

With these and other objects in view which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts hereinafter more fully described and claimed, illustrated in the accompanyin drawing, in which like characters of re erence indicate like parts throughout the several figures of which Figure 1 represents a perspective view of Referring more particularly to the draw- Patented Mar. 2, 1915.

ing, 5 indicates the slide rods of a well known type of bottle washing machine, known as the Goulding bottle washing machine, 6 indicates the yoke carried at the forward ends of the slide rods, 7 indicates the, nozzle carried in fixed relation by the yoke and extending at one end forwardly of said yoke, 8 indicates the mouth piece which is carried on the front end of the yoke, and 9 indicates the spindle which is driven at a high rate of speed and which carries a brush (not shown),which brush when the machine is not in the process of cleaning a bottle, is housed within nozzle 7, but which is uncovered by the housing when a bottle mouth is placed against the mouth piece as indicated at Fig. 2, upon the bottle being shoved so as to move the yoke rearwardly, said brush as it is uncovered entering the neck of the bottle and extending into and spreading within the bottle, and cleansing the same as the brush rotates with the spindle. The pressure upon the bottle hav ing been relieved the yoke is carried forward by means of a spring (not shown) so that the brush is again housed within the nozzle, said forward motion of the yoke withdrawing or moving the bottle from the brush.

lhe attachment which forms the subject of this invention comprises a bridge 10 secured to cross piece 11 of the yoke, which cross piece carries the rear end of nozzle 7 by means of a screw 12, which in'the usual machine serves to secure a water guard over the rear end of the nozzle, which water guard is dispensed with when my improved attachment is used. One end of bridge 10 is provided with a pair of spaced ears 13, between which is pivoted the lower end of an arm 14, said arm carrying at itsupper actin with a disk end a grease box 15 in which is journaled near its rear end a shaft 16, the forward end of which is j ournaled in a grease box 17 carried at the outer end of an arm 18 attached to arm l-l. The rear end of shaft 16 carries a disk 19, to which is secured by means of screws or other removable fastening means 20, a wood or composition or other suitable friction wheel 21, bearing upon and driven by spindle 9 as the latter rotates. The opposite end of bridge 10 from ears 13, is provided with a staple or eye 22, to which one end of a retractile spring 23 is connected, the opposite end of said spring being connected to a clip provided with an opening by means of wnich the clip may be slipped over a pin 25 carried by grease box 15, the function of the spring being to maintain the friction wheel at all times in contact with the'spindle, and also to take up the wear occurring in the friction wheel through constant use. Carried by the forward end of shaft 16, is a driving pulley 26 over which runs an elastic driving belt 27.

The brush holder comprises a sleeve 28 adapted to l e slipped upon the forward end of nozzle 7 subsequently to the removal of mouth piece 8, which mouth piece may be then replaced, said sleeve being provided in ternally with an annular groove 29 adapted to be filled with lubricating gr ass, and provided further at its rear end with an annular flange 30 adapted to bear against the forward face of the yoke 6, said flange 30 oo- 31 formed on the opposite end of the sleeve, in forming a guioeway for belt 27 whereby the sleeve may be rotated with the nozzle as a bearing, as the friction wheel is driven. A pair of oppositely extending similar forwardly curved arms 32 are formed on disk 31-, and at their outer ends are provided with lugs 33 having openings 34: extending therethrough in which openings the brushes 35 are disposed. Said brushes are formed of straight pieces of steel wire, at their outer ends set in a suitable knob 36 affording a finger hold for the brushes, and adapted to maintain them in fixed relation with each other, said brushes, as shown, being disposed oppositely to each other, with their inner ends 37 directed toward the axis of and spaced slightly from the mouth piece 3, in position as indicated in Fig. 2 to engage the crown groove and adjacent portions of a bottle neck when the bottle mouth is placed against mouth piece 3 in the initial operation of cleaning the bottle. Set screws 38 are carried by lugs 33, and are adapted to be turned into engagement with the brushes 35 to maintain said brushes in fixed relation to the lugs, said screws adapted to be unloosened when the brushes wear away whereby the brushes may be at vanced to take up the wear.

Through the connection of the friction disk, the shaft pulley and elastic belt, the sleeve 23 and hence the brushes 35 are rotated at a high rate of speed relatively to the mouth piece against which the bottle mouth bears, and thus the rust accumulated in and about the crown groove of the bottle neck is removed, simultaneously with the cleansing of the interior of the bottle by the brush (not shown) carried by the spindle. As before stated the yoke and parts associated therewith reciprocate longitudinally of the spindle during the operation of cleaning bottles, and as they move relatively to the spindle the friction wheel 21 slides on said spindle but it is always maintained in contact therewith so as to impart steady and uniform power to the brushes by means of the spring 23. It will be noted that brushes 35 rotate in a direction contrary to the direction of rotation of the spindle and the brush carried by said spindle, so that the tendency of the spindle brush and the brushes 35 to rotate the bottle, is counteracted by the contrary rotation of the brushes so that no extra force need be exerted by the operator for maintaining the bottle in a fixed position.

The brushes are disposed at an angle to each other and not in alinement with each other, and are so positioned at their inner ends as to engage well within the croan groove so as to insure positive cleansing thereof.

Although I have described the preferred embodiment of my invention, 1 desire to make such changes in the construction, combination and arrangement of parts thereof as do not depart from the spirit of the invention and the scope of the appended claims.

l claim.
